PCI

Short for Peripheral Component Interconnect, PCI was introduced by Intel in 1992, revised in 1993 to version 2.0, and later revised in 1995 to PCI 2.1 and is as an expansion to the ISA bus. Below is a graphic illustration of the PCI slot on a motherboard.

The PCI bus is a 32-bit computer bus that is also available as a 64-bit bus and is the most commonly found and used computer bus in computers today.
